Both my GT and the g/f's V6 are hopefully coming out of hibernation in 2 weeks after 4 months but I placed battery tenders on both. Hopefully they'll start up like yours did, stoenr. The battery in the g/f's '06 was beginning to look suspicious before it went into storage. We'll see what the battery tender did over the long-term. But most probably I'll be replacing her battery anyway since it's the OE.
